MODE OF THE INVENTION

Embodiments of the present invention now will be described more fully hereinafter with reference to the accompanying drawings. The present invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Numerous modifications and adaptations will be readily apparent to one of ordinary skill in this art from the detailed description and the embodiments without departing from the scope of the present invention.

FIG. 1 is a conceptual diagram illustrating a system 100 for providing medical information according to an embodiment of the present invention.

Referring to FIG. 1, the system 100 includes a cloud 110 and a user 130. Although the term ‘user’ is used for convenience of explanation in FIG. 1, the user 130 means an apparatus used by the user 130 and encompasses an external apparatus that may access the cloud 110. Also, the cloud 110 may be a predetermined server to which one or more external apparatus may make access through wired/wireless communication.

The system 100 according to an embodiment of the present invention refers to a system that generates medical information of an object based on the cloud 110 and provides the medical information to the user 130. The object may be, but not limited to, a patient who is required to be diagnosed.

In detail, the system 100 may generate medical information of an object based on an open platform and may provide the medical information to the user 130. For example, the system 100 includes a platform that provides various services 120 such as medical information search, storage, transmission, inquiry, or exchange based on the medical information standard such as Integrating the Healthcare Enterprise (IHE), Digital Imaging and Communications in Medicine (DICOM), or Health Level-7 (HL7) and the international standard such as Word Wide Web Consortium (W3C) or International Organization for Standardization (ISO).

For example, the services 120 provided by the system 100 may include a medical information providing or processing service, a tele-medicine service, a clinical decision supporting system service, a medical information storing or sharing service, a server-side computing service, and a social networking service. However, the services 120 are not limited to the above services, and may be any service provided by the system 100 according to an embodiment of the present invention as long as a work may be done by a user by using the medical information due to the service.

A system 200 for providing medical information will now be explained with reference to FIG. 2.

FIG. 2 is a diagram for explaining the system 200 according to an embodiment of the present invention.

Services 210 provided by the system 200, an external filter 220, and an architecture 230 of a cloud are illustrated in FIG. 2. An infrastructure 2310, an internal filter 2320, a data storage 2330, a controller 2340, a platform-level application programming interface (API) 2350, a service-specific API 2360, and a user interface 2370 are included in the architecture 230. A dataset handler 2341, a workflow manager 2342, a patient manager 2343, a user manager 2344, a group manager 2345, and a condition manager 2346 are included in the controller 2340. Also, although not shown in FIG. 2, a filter manager is further included in the controller 2340.

Types of the services 210 are the same as those described with reference to FIG. 1. Accordingly, a detailed explanation of the types of the services 210 will not be given.

The external filter 220 refers to a filter that operates outside the cloud. In detail, the external filter 220 performs an operation outside a database of the cloud. For example, the external filter 220 may be included in at least one apparatus from among external apparatuses connected to the cloud. In this case, information about the external filter 220 may be generated, set, changed, and deleted by the filter manager of the architecture 230 and may be transmitted to the external apparatus, or may be generated, set, changed, and deleted by the external apparatus. The external filter 220 according to an embodiment of the present invention will be explained below in detail with reference to FIGS. 5 and 6.

The architecture 230 of FIG. 2 is an architecture that may be constructed in the cloud 110 of FIG. 1. Accordingly, it will be understood by one of ordinary skill in the art that general-purpose elements other than the elements illustrated in FIG. 2 may be further included.

Also, the infrastructure 2310, the data storage 2330, the controller 2340, the platform-level API 2350, the service-specific API 2360, and the user interface 2370 included in the architecture 230 of FIG. 2 may correspond to one or more processers. Each processor may be an array of logic gates, or a combination of a general-purpose microprocessor and a memory storing a program that may be executed by the microprocessor. Also, it will be understood by one of ordinary skill in the art that the processor may be another type of hardware.

The data storage 2330 stores and manages all types of content that may be processed by the cloud. The content used herein refers to any type of document including text, an image, or a video. In other words, examples of the content may include all types of documents, such as images, waveforms, and measured values, which may be processed by general arithmetic units. Accordingly, content and a document in an embodiment of the present invention are described as the same concept.

In the system 200 according to an embodiment of the present invention, one document may be included zero or more document sets DocSet. In other words, a document may not be included in a document set or may be included in one or more document sets. Also, a specific document has to belong to one group. The group used herein may refer to a group of a real organization such as a hospital or a department/division, or a virtual user set. The group will be explained below in detail. An ID for identifying each document is assigned in the cloud. An ID type related to a document and a definition thereof according to an embodiment of the present invention are shown in Table 1.

TABLE 1 ID type Definition Document Is a unique ID of a document, and is unique in a specific UID group that generates the document. Document Is a unique ID separate from the Document UID, and is UUID unique in all documents. For example, there is one Document UID for a first document whereas a Document UUID may vary whenever the first document is transmitted (or processed). Filter UID Is an ID indicating a filter that generates the document. Patient Id Is an ID indicating a patient related to the document.

Each of all documents according to an embodiment of the present invention has a unique ID (UID), and the UID guarantees uniqueness only in a specific group. Also, each of all documents has a unique UUID separate from the UID and guarantees uniqueness in all of the documents. A document in the cloud according to an embodiment of the present invention corresponds to a document entry in an Integrating the Healthcare Enterprise (IHE) Cross Enterprise Document Sharing (XDS).

The dataset handler 2341 manages a document set. In detail, the dataset handler 2341 generates, sets, changes, and deletes a document set. The document set DocSet refers to a virtual set of real documents. Any processing in the cloud is performed in units of document sets. Also, a specific document set has to belong to one group. An ID for identifying each document set is assigned in the cloud. An ID type related to a document set and a definition thereof according to an embodiment of the present invention are shown in Table 2.

TABLE 2 ID type Definition DocSet Is a unique ID of a document set, and is unique in a specific UID group that generates the document set. DocSet Is a unique ID separate from the document set UID, and is UUID unique in all document sets. For example, there is one document set UID for a first document set whereas a document set UUID may vary whenever the first document set is transmitted (or processed). DocSet Indicates a type of a document set, and is used to designate Class UID an input/output method of a filter. DocSet Is used to express a relationship between document sets. Group UID Filter UID Indicates a filter that generates the document set. Patient Id Indicates a patient related to the document set.

A document set in the cloud according to an embodiment of the present invention corresponds to a submission set in the IHE XDS.

Also, a document set has to have one document set class DocSet Class. The document set class used herein refers to a class of a document set. The document set class is used to designate an input/output method of a filter, and is expressed with a unique document set class UID that is unique in the cloud.

The workflow manager 2342 manages a workflow that operates in the cloud. In detail, the workflow manager 2342 generates, sets, changes, and deletes a workflow. A workflow according to an embodiment of the present invention will be explained below in detail with reference to FIG. 4.

The patient manager 2343 manages information about a patient. In detail, the patient manager 2342 generates, sets, changes, and deletes patient information. The patient refers to an owner of medical information or health information, and is different from a user that is another entity using the medical information. In reality, the patient receives different patient numbers according to organizations (e.g., hospitals or governments). Accordingly, the patient in the cloud may be expressed with different patient numbers in a plurality of groups and the linking of the different patient numbers may indicate the same patient.

The user manager 2344 manages information about a user. In detail, the user manager 2344 generates, sets, changes, and deletes user information. The term ‘manage’ used herein includes actions of generating, changing, and deleting patient information. The user refers to a user who uses services of the cloud and is different from the patient. For example, the user may be a medical staff member such as a doctor or a nurse, or may be a government official sometimes.

One user may belong to zero or more groups. In other words, the user may not belong to any group, or may belong to one or more groups. If the user belongs to one or more groups, the user may be given a group manager right. A right to search for and inquire about the afore-described document set may be given to an individual user. A user according to an embodiment of the present invention may be authenticated by a method of the system 200 itself or may be authenticated by a service provider that provides other authentication services.

The group manager 2345 manages information about a group. In detail, the group managers 2345 generates, sets, changes, and deletes group information. The group refers to a set of users. According to a configuration, the group may refer to a group of a real organization such as a hospital or a department/division, or a virtual user set.

The group may be an independent group or may be a group under one higher group. Also, the group may include a plurality of users. The group may give a manager right to manage the group to a specific user included in the group. In this case, the right to manage the group is inherited to sub-groups of the group. In other words, a manager of the specific group may also manage the sub-groups of the group.

A right to search for and inquire about a document set may be indirectly given through the group to which the user belongs. However, the right to search for and inquire about the document set is valid only in the designated group, and is not inherited to the sub-groups of the group.

The condition manager 2346 manages conditions set on the system 200. In detail, the condition manager 2346 generates, sets, changes, and deletes conditions. The conditions may correspond to a document set condition DocSet rule and/or a filter condition. The filter condition may be generated, set, changed, and deleted by the condition manager 2346, or may be generated, set, changed, and deleted by the filter manager.

In detail, the document set condition refers to a condition used to automatically give a right to search for and inquire about a specific document set to a user. Also, the filter condition refers to a condition used to automatically perform an operation of a filter. The internal filter 2320 or the external filter 220 may be included in the filter according to an embodiment of the present invention. In detail, the internal filter 2320 performs an operation in the database of the cloud. In this case, information about the internal filter 2320 is generated, set, changed, and deleted by the filter manager of the architecture 230.

A filter class, a filter condition, a filter queue, and a filter log related to the filter will now be explained in detail.

First, the filter class refers to a class of the filter, and an input/out method is expressed by using a document set class. One filter class may correspond to a plurality of filters. That is, there may be various filters having the same input/output method and function.

An input and an output of the filter may be expressed with zero or more document set classes. In detail, the filter may receive one document set and may output one document set, and may receive a plurality of documents sets and may generate a plurality of output document sets. Also, the filter may have an output function without having an input function or may have an input function without having an output function.

The internal filter 2320 refers to a filter that performs an operation in the database of the cloud, and may be a stored function of a database of the infrastructure 2310. The external filter 220 refers to a filter that performs an operation outside the database of the cloud and may operate by using the APIs 2350 and 2360 provided by the cloud.

The filter indicates an instance of the filter and indicates an actual instance of the filter expressed with a filter class. All filters having the same filter class UID may perform substantially the same function.

However, a default group and a default patient may be differently designated according to each filter. For example, the filter manger may automatically set a group of documents and a document set generated by the filter by designating a default group. Also, the filter manager may automatically set a patient of a document and a document set generated by the filter by designating a default patient.

The filter condition refers to at least one condition required to operate the filter. When the filter condition is satisfied, the filter automatically performs an operation. If a plurality of document sets are needed to operate the filter, a condition may be set according to each of the document sets.

For example, a time when the filter performs an operation may be designated as follows.

For example, an absolutely designed specific date and time (e.g., Apr. 5, 2014, 03:00 P.M.)

Alternatively, a predetermined period of time after the filter condition is satisfied (e.g., 5 hours after the filter condition is satisfied)

Alternatively, a predetermined period of time after the beginning (00:00 A.M.) of the day after the condition is satisfied (e.g., assuming that the condition is satisfied on Apr. 5, 2014, 03:00 P.M., 5 hours after Apr. 6, 2014, 00:00 A.M.)

When the filter condition is satisfied, the filter manager (or the condition manager 2346) registers the filter that is to perform an operation and necessary document sets in the filter queue and designates a time when the filter is to perform the operation. If the time when the filter is to perform the operation is not specified, the filter immediately performs the operation.

The filter queue refers to a wait queue for operating the filter. The internal filter 23320 processes content of the filter queue at a designated time interval (e.g., 60 seconds). The external filter 220 processes content of the filter queue according to filter procedure (FilterProc) module settings.

The filter log refers to a log about processing (action) of the internal filter 2320.

The internal filter 2320 and the external filter 220 according to an embodiment of the present invention will be explained below in detail with reference to FIGS. 5 through 6.

The user interface 2370 refers to a user interface for managing the cloud and searching for and inquiring about information. For example, the user interface 2370 may be a web-based interface.

The platform-level API 2350 refers to an API collection for directly interfacing between the cloud and external apparatuses. Also, the service-level API 2360 refers to an API collection based on the platform-level API 2350 for a specific service (e.g., a service A) from among the services 210 provided by the system 200.

The infrastructure 2310 refers to an infrastructure for providing all of the afore-described services of the cloud. For example, the infrastructure 2310 may correspond to, but not limited to an Amazon Web Services cloud service.

The cloud having the architecture 230 may generate and provide medical information of an object (e.g., a patient) based on an open platform, and may provide the medical information of the object to a user without time and space constraints.

FIG. 3 is a flowchart for explaining an operation of a system for providing medical information (referred to as the medical information providing system) according to an embodiment of the present invention.

Referring to FIG. 3, an operation of the medical information providing system includes steps that are sequentially performed by the system 100 or 200 or the cloud 110 of FIGS. 1 and 2. Accordingly, although omitted, the description of the medical information providing system or the cloud 110 of FIGS. 1 and 2 may apply to the operation of the medical information providing system of FIG. 3.

For convenience of explanation, it is assumed that each of the steps of FIG. 3 is performed by the ‘cloud 110’. However, it will be understood by one of ordinary skill in the art that an entity that performs each of the steps of FIG. 3 may be any of the elements included in the architecture 230 of FIG. 2.

In step 310, the cloud 110 generates and sets group information.

First, the cloud 110 generates a group (hereinafter, referred to as a master group) that represents an organization that is to open a service, based on an external signal input from a user. Organizations such as real hospitals may be generated under the master group. For example, the cloud 110 may generate a group as shown in Table 3.

TABLE 3 Group hierarchy Group: Radionet top group: master group Group: SNUH primary child group: medical institution Group: Radiology secondary child group: department in medical institution Group: CMC primary child group: medical institution Group: Cardiology secondary child group: department in medical institution Group: GuroClinic primary child group: medical institution

Referring to Table 3, the cloud 110 may generate a master group Rradionet, and may generate real medical institutions such as Seoul National University Hospital (SNUH), Catholic Medical Center (CMC), and Guro Clinic as child groups under the master group Radionet. Also, after forming the real medical institutions as groups, the cloud 110 may register departments in the medical institutions as other child groups Radiology and Cardiology.

A database table structure for storing group information is shown in Table 4.

TABLE 4 Table “VGroup” Column Type Modifiers vgroup_key integer not null PK vgroup_id character varying(64) not null UK vgroup_id_type character varying(16) not null UK vgroup_name character varying(256) vgroup_type character varying(64) parent_vgroup_key integer FK created_dttm timestamp without time zone not null deleted_dttm timestamp without time zone

A detailed description of attributes included in the table structure of Table 4 is shown in Table 5.

TABLE 5 Attribute Description Group Id Indicates an ID of a group, and sets assigning_authority_id that is one of three elements constituting a patient number to Group Id. It may be expressed by using, but not limited to, ISO OID. For example, when a medial institution code such as 82999 is given, it indicates a 999^(th) hospital in Korea (82). Group Id Indicates a type of the ID of the group, and sets Type assigning_authority_id_type that is one of three elements constituting the patient number to Group Id Type. When a group ID is registered by using ISO OID, ISO has to be designated. However, otherwise, self-determination may be used. For example, Group Id Type may be set to “BIS-CLOUD”. Group Indicates a name of the group that may be recognized by a Name person. For example, it may be set to an official name of a medical institution. Group Indicates an item for indicating a type of the group. For Type example, a hospital may be set to “HOSPITAL”, and a clinic may be set to “CLINIC”. Parent Indicates a parent group. Group

In step 320, the cloud 110 generates and sets user information.

The cloud 110 generates a user (hereinafter, referred to as a master manager) who is to manage the master group, based on an external signal input from the user. The cloud 110 gives a right to manage the master group to the master manager. In the medical information providing system according to an embodiment of the present invention, when one user has a right to manager a certain group (that is, is a group manager), the user may manage sub-groups of the group. Accordingly, when the master manager has a right to manage a master group, it means that the master manager may generate a plurality of groups under the master group. Only a group manager may add a user or a patient to the group or child groups of the group.

For example, an example where a group manager is set according to a group is shown in Table 6.

TABLE 6 Group hierarchy group manager Group: Radionet bioadmin  Group: SNUH bioadmin, snuhadmin  Group: Radiology bioadmin, snuhadmin, snuhradioadmin  Group: CMC bioadmin, cmcadmin  Group: Cardiology bioadmin, cmcadmin  Group: GuroClinic bioadmin, gurocadmin

Referring to Table 6, a master manager bioadmin may manage both a group Radionet and child groups. A group manager snuhadmin may manage a group SNUH and a group Radiology that is a child group of the group SNUH. If a separate manager is necessary for the group Radiology, a group manager snuhradioadmin may be additionally designated as shown in Table 6.

A user in the medical information providing system according to an embodiment of the present invention may belong to a plurality of groups. In this case, when the user belongs to a specific group and is given a management right, the user becomes a manger of the group and, otherwise, becomes a general user. After a group manager is generated, the cloud 110 generates as many general users as needed and makes the general users belong to groups.

However, an inquiry right, unlike a management right that is inherited, is not inherited. That is, when a user is to inquire about a document of a group, the user has to belong to the group. For example, referring to Table 6, the group manager snuhadmin may manage the group SNUH and the group Radiology, but may not inquire about a document of the group Radiology. In order for the user snuhadmin to inquire about the document of the group Radiology, the user snuhadmin has to belong to the group Radiology.

The user may have a plurality of authentication methods. For example, the user may log on through self authentication of the medical information providing system, or may log on by using other authentication accounts (e.g., a Google account).

A database table structure for storing user information is shown in Table 7.

TABLE 7 Table “Users” Column Type Modifiers user_key integer not null PK user_name character varying(256) not null created_dttm timestamp without time zone not null deleted_dttm timestamp without time zone

A database table structure for setting a relationship between a group and a user is shown in Table 8.

TABLE 8 Table “VGroupUser” Column Type Modifiers vgroup_user_key integer not null PK vgroup_key integer not null FK user_key integer not null FK admin_role Boolean default false

In step 330, the cloud 110 generates and sets patient information.

The cloud 110 may generate and set patient information, based on an external signal input from the user. In the medical information providing system according to an embodiment of the present invention, a patient may have attributes such as a patient number, a name, a sex, and a birthdate. From among the attributes, the patient number includes three parts patient_id_value, assigning_authority_id, and assigning_authority_id type. In this case, the parts assigning_authority_id and assigning_authority_id type correspond to the attributes Group Id and Group Id Type of the group, and patient_id_value indicates the patient number of the group. Accordingly, the patient in the medical information providing system according to an embodiment of the present invention belongs to only one group.

A database table structure for storing the patient information is shown in Table 9.

TABLE 9 Table “Patient” Column Type Modifiers patient_key integer not null PK vgroup_key integer not null FK patient_id_value character varying(64) not null patient_name character varying(256) not null patient_sex character varying(1) patient_birth_dttm timestamp without time zone related_patient_key integer FK created_dttm timestamp without time not null zone deleted_dttm timestamp without time zone

A detailed description of attributes included in the table structure of Table 9 is shown in Table 10.

TABLE 10 Attribute Description Patient Id Indicates patient_id_value that is a first part from among Value three parts of a patient number. Patient Indicates a name of a patient. For example, it may be Name input by using a HL7 method (Last name{circumflex over ( )}First name{circumflex over ( )}Middle name{circumflex over ( )}Suffix{circumflex over ( )}Prefix). Patient Sex Indicates a patient sex. For example, it may be input as ‘M = male, F = female, O = other, or U = unknown’. Patient Indicates a birthdate of the patient. Birthdate Related Indicates connection with other patient information. Patient

Even the same patient may go to a plurality of medical institutions. In this case, different patient numbers may be assigned to the same patient according to medical institutions. Accordingly, the medical information providing system according to an embodiment of the present invention generates a patient according to each medical institution. However, patient attributes in the medical information providing system include an attribute Related Patient as shown in Table 10, and thus other patient information may be connected. In other words, the cloud 110 may find and connect pieces of information about the same patient distributed in medical institutions by using the attribute Related Patient.

In step 340, the cloud 110 designs a workflow based on an external signal input from a manager of the cloud 110.

The workflow is the flow of an operation performed by at least one filter. The medical information providing system according to an embodiment of the present invention generates medical information of an object (e.g., a patient) according to the workflow, and provides the medical information to a user. A workflow will now be explained with reference to FIG. 4.

FIG. 4 is a view illustrating a workflow 400 according to an embodiment of the present invention.

The workflow 400 designed by the cloud 110 is illustrated in FIG. 4. Although the workflow 400 is illustrated in FIG. 4 for convenience of explanation, the workflow 400 designed by the cloud 110 is not limited to that of FIG. 4. In other words, any workflow in which medical information of an object (e.g., a patient) may be generated by using at least one filter belonging to at least one filter set or a single filter set and may be provided to a user may be included in the scope of the present invention without limitations.

A circular portion in the workflow 400 of FIG. 4 refers to a document set class DSC. At least one document may be included in one document set. Accordingly, it will be understood by one of ordinary skill in the art that although a specific document set class is described in each circular portion of FIG. 4, the same applies to another document belonging to the document set. The document set class, the document set, and the document are the same as those described with reference to FIG. 2, and thus a detailed explanation thereof will not be given.

Also, a rectangular portion in the workflow 400 of FIG. 4 refers to a filter class FC and a filter FU included in the filter class. At least one filter may be included in one filter class. Accordingly, it will be understood by one of ordinary skill in the art that although a specific filter class and a filter are described in each rectangular portion of FIG. 4, the same applies to another filter included in the filter class. The filter class and the filter are the same as those described with reference to FIG. 2, and thus a detailed explanation thereof will not be given.

Also, detailed names of the document set class, the filter class, and the filter of FIG. 4 are added for convenience, and thus the present invention is not limited thereto.

A filter 4.1 410 that is one instance of a filter class 3.1 generates one or more from among four document sets EKG 411, Holter 412, Event Recorder 413, and DICOM 414. The filter 4.1 410 may be an external filter that generates a document set, or may be an internal filter that generates a document set by using a signal received from an external apparatus. The document set EKG 411 expressed with a document set class 5.1 may be stored in the data storage 2330.

A filter 4.2.1 420 that is one instance of a filter class 3.2.1 receives the document set Holter (document set class 5.2) 412 and outputs a document set Clinical Decision Supporting System (CDSS) Results (a document set class 5.2.1) 421.

A filter 4.2.2 450 that is one instance of a filter class 3.2.2 generates a new document set (a document set class 5.2.2) 451 by combining the document set Holter 412 with the document set CDSS Results 421.

A filter 4.2 430 that is one instance of a filter class 3.2 combines the document set Event Recorder 413 that is expressed with a document set class 5.3.

A filter 4.4.1 440 that is one instance of a filter class 3.4.1 provides the document set DICOM 414 that is expressed with a document set class 5.4 to an external apparatus. The external apparatus displays the document set DICOM 414 on a screen. The displayed document set 441 may be checked by the cloud 110.

Referring back to FIG. 3, in step 350, the cloud 110 sets a document set class. In other words, the cloud 110 sets a document set class that is needed to operate the workflow 400 that is designed in step 340.

The cloud 110 assigns a UID to each document set and a filter and sets the UID in the medical information providing system. For example, the filter class 3.1 410 and the document set class 5.1 411 of FIG. 4 may be respectively expressed with UIDs such 1.2.410.200054.3.1 and 1.2.410.200054.5.1. The setting of the document set class is completed when the UID and a name of the document set class are designated.

A database table structure for storing document set class information is shown in Table 11.

TABLE 11 Table “DocSetClass” Column Type Modifiers docset_class_uid character varying(64) not null PK docset_class_type character varying(10) not null docset_class_name character varying(256) not null

A detailed description of attributes included in the table structure of Table 11 is shown in Table 12.

TABLE 12 Attribute Description DocSet Class Indicates a UID of a document set class, and a unique UID UID is assigned to each document set class. DocSet Class Indicates a type of the document set class and is used only Type for reference. DocSet Class Indicates a name of the document set class. Name

In step 360, the cloud 110 sets a filter class. In other words, the cloud 110 sets a filter class that is needed to operate the workflow 400 designed in step 340.

In order for the cloud 110 to set the filter class, several additional attributes are further necessary in addition to a filter class UID and a filter class name.

A database table structure for storing filter class information is shown in Table 13 and Table 14.

TABLE 13 Table “FilterClass” Column Type Modifiers filter_class_uid character varying(64) not null PK filter_class_name character varying(256) not null filter_type character varying(10) not null filter_proc_name character varying(256) filter_proc_args character varying(256)

TABLE 4 Table “FilterInOut” Column Type Modifiers filter_class_uid character varying(64) not null PK, FK docset_type character varying(1) not null PK docset_class_uid character varying(64) not null PK, FK

A detailed description of attributes included in the table structure of Table 13 and Table 14 is shown in Table 15.

TABLE 15 Attribute Description Filter Class UID Is a UID of a filter class, and a unique UID is assigned to each filter class. Filter Class Name Indicates a name of the filter class. Filter Class Type Indicates a type of the filter class and indicates an internal filter I or an external filter E. Filter Proc Name Is set only in the internal filter and is a name of a database procedure. Filter Proc Args Is set in the internal filter and is factors of the database procedure. DocSet Type Indicates whether a designated document set is an input I or an output O of a filter. DocSet Class Designates an input or output document set of the UID filter.

Also, the cloud 110 sets an input document set and an output document set that may be processed by each filter class.

For example, the cloud 110 may set a filter class as shown in Table 16.

TABLE 16 filter_class_name filter_proc_name filter_class_uid    docset_type type docset_class_uid 1.2.410.200054.3.1 data uploader E    O 1.2.410.200054.5.1    O 1.2.410.200054.5.2    O 1.2.410.200054.5.3    O 1.2.410.200054.5.4 1.2.410.200054.3.2 Holter data creator E    I 1.2.410.200054.5.3 1.2.410.200054.3.2.1 CDSS caller E    I 1.2.410.200054.5.2    O 1.2.410.200054.5.2.1 1.2.410.200054.3.2.2 data merger I FilterQueue_bypass    I 1.2.410.200054.5.2    I 1.2.410.200054.5.2.1    O 1.2.410.200054.5.2.2 1.2.410.200054.3.4.1 DICOM viewer E    I 1.2.410.200054.5.4    O 1.2.410.200054.5.4.1

In step 370, the cloud 110 sets a filter. In other words, the cloud 110 sets a filter that is needed to operate the workflow 400 designed in step 340.

A database table structure for storing filter information is shown in Table 17.

TABLE 17 Table “Filter” Column Type Modifiers filter_key integer not null PK filter_uid character varying(64) not null UK filter_class_uid character varying(64) not null FK filter_name character varying(256) not null filter_proc_args character varying(32) default_vgroup_key integer FK default_patient_key integer FK user_key integer FK created_dttm timestamp without time not null zone deleted_dttm timestamp without time zone

A detailed description of attributes included in the table structure of Table 17 is shown in Table 18

TABLE 18 Attribute Description Filter UID Indicates a UID of a filter and is a unique value for each filter. Filter Class UID Indicates a type of the filter and sets a filter class UID. Filter Name Indicates a filter name. Filter Proc Args Re-defines factors of a database procedure that is used in an internal filter. Default Group Indicates a group that is automatically set when there is no group information in a document set processed by the filter. Default Patient Indicates a patient that is automatically set when there is no patient information in the document se processed by the filter.

For example, the cloud 110 may set a filter as shown in Table 19.

TABLE 19 filter_uid filter_class_uid filter_name 1.2.410.200054.4.1.2.152.82.177.100.84.74.1598 1.2.410.200054.3.1 Bioroid02(ejoonie) 1.2.410.200054.4.1.2.152.82.177.100.84.74.1582 1.2.410.200054.3.1 Bioroid 1.2.410.200054.4.1.2.20.137.253.246.167.124.1347 1.2.410.200054.3.1 Bioroid 1.2.410.200054.4.1.2.152.82.177.100.84.74.2289 1.2.410.200054.3.1 Bioroid 1.2.410.200054.4.1.2.20.137.253.246.167.124 1.2.410.200054.3.1 Bioroid 1.2.410.200054.4.1 1.2.410.200054.3.1 BioPump 1.2.410.200054.4.1.2.152.82.177.100.84.74 1.2.410.200054.3.1 Bioroid (ejoonie) 1.2.410.200054.4.1.2.12.223.164.47.47.236 1.2.410.200054.3.1 Bioroid 1.2.410.200054.4.1.2.8.212.43.25.38.81 1.2.410.200054.3.1 Bioroid 1.2.410.200054.4.2 1.2.410.200054.3.2 EventMerge 1.2.410.200054.4.2.1 1.2.410.200054.3.2.1 HolterExport 1.2.410.200054.4.2.2 1.2.410.200054.3.2.2 SimpleMerge 1.2.410.200054.4.4.1 1.2.410.200054.3.4.1 ezDICOM

In step 380, the cloud 110 sets a filter condition.

If the cloud 110 does not set a filter condition, document sets may be simply stored but the workflow 400 of FIG. 4 may not be obtained. The filter condition includes i) setting of a filter that is to perform an operation and ii) setting of an input condition for performing the operation of the filter.

First, when the input condition of the filter is satisfied, a database table structure for storing information of the operation to be performed by the filter is shown in Table 20.

TABLE 20 Table “FilterRule” Column Type Modifiers filter_rule_key integer not null PK filter_key integer not null FK filter_rule_name character varying(256) scheduled_dttm timestamp without time zone scheduled_delay integer created_dttm timestamp without time zone not null deleted_dttm timestamp without time zone

A detailed description of attributes included in the table structure of Table 20 is shown in Table 21.

TABLE 21 Attribute Description Filter Rule Name Indicates a name of a filter rule. Filter Selects a filter that is to perform an operation. Scheduled Time Designates an absolute time when the filter is to perform the operation, and the filter performs the operation on the designed time. The designating of the absolute time is performed before a relative time is designated. Scheduled Delay Designates the relative time when the filter is to perform the operation, and the filter performs the operation a designated period of time after a current time in a a) mode, or, a designated period of time after tomorrow 00:00 A.M. in a b) mode. For example, assuming that a current time is February 5, 2014, 18:00 and an attribute Scheduled Delay is 3:00, the filter performs the operation on February 5, 2014, 21:00 in the a) mode and the filter performs the operation on February 6, 2014, 3:00 in the b) mode.

Next, a database table structure for setting the input condition of the filter is shown in Table 22.

TABLE 22 Table “FilterRuleInput” Column Type Modifiers filter_rule_input_key integer not null PK filter_rule_key integer not null FK, UK docset_class_uid character varying(64) not null FK, UK filter_key integer FK, UK vgroup_key integer FK, UK patient_key integer FK, UK

A detailed description of attributes included in the table structure of Table 22 is shown in Table 23.

TABLE 23 Attribute Description Filter Rule Selects a filter condition. DocSet Class UID Sets which document set is to be prepared to perform an operation of a filter. Filter Sets which filter is to generate the document set. Group Sets which group the document set is to belong to. Patient Sets which patient is to own the document set.

Referring to the workflow 400 of FIG. 4, the workflow is needed to be set only for the document set Holter 412 and the document set DICOM 414. This may be obtained when the cloud 110 sets as shown in Table 24.

TABLE 24   filter_uid scheduled_dttm delay filter_rule_name docset_class_uid filter vgroup patient HolterExport rule   1.2.410.200054.4.2.1 1.2.410.200054.5.2 Merger rule   1.2.410.200054.4.2.2 1.2.410.200054.5.2 1.2.410.200054.5.2.1 ezDICOM rule   1.2.410.200054.4.4.1 1.2.410.200054.5.4

When a new document set is generated, a function FilterRule_apply( ) is automatically called. In this case, the cloud 110 searches for a filter condition to determine whether there is a filter to be applied to the new document set and records a result on a filter queue. If an input condition of the filter condition includes only one document set, the filter condition is used as soon as the document set satisfying the condition is generated. However, when the input condition of the filter condition includes a plurality of document sets (that is, when the filter has to process a plurality of documents sets at one time), the filter condition is used when all of the document sets needed to perform an operation of the filter are prepared.

Content of Table 24 will now be explained as follows.

1) According to a filter condition “HolterExport rule”, a filter 1.2.410.200054.4.2.1 performs an operation as soon as a document set for a document set class 1.2.410.200054.5.2 is prepared.

2) According to a filter condition “Merger rule”, a filter 1.2.410.200054.5.2.2 performs an operation when all document sets for document set classes 1.2.410.200054.5.2 and 1.2.410.200054.5.2.1 are prepared.

3) According to a filter condition “ezDICOM rule”, a filter 1.2.410.200054.4.4.1 performs an operation when a document set for a document set class 1.2.410.200054.5.4 is prepared.

In step 390, a filter queue is generated. The filter queue is not set but is generated as a result of using the filter condition, and stores pieces of information about the filter that is to perform an operation and a result of the operation of the filter.

The filter queue includes i) storing of information about the filter that is to perform an operation and ii) storing of information about a document set that is to be input to the filter.

First, a database table structure for storing information about a filter that is to perform an operation is shown in Table 25.

TABLE 25 Table “FilterQueue” Column Type Modifiers filter_queue_key integer not null PK filter_queue_uuid uuid not null UK filter_key integer not null FK filter_result_text text filter_result_code integer scheduled_dttm timestamp without time zone performed_dttm timestamp without time zone created_dttm timestamp without time zone not null

A detailed description of attributes included in the table structure of Table 25 is shown in Table 26.

TABLE 26 Attribute Description Filter Queue UUID Is a UUID of a filter queue, and is used to process a filter operation by using an XDS method. Filter Designates a filter that is to perform an operation. Filter Result Text Indicates a result of the operation of the filter. Filter Result Code Indicates a result code of the operation of the filter. Scheduled Time Indicates a time when the filter is to perform the operation. Performed Time Indicates a time when the filter performs the operation.

Next, a database table structure for storing information about a document set that is to be input to a filter is shown in Table 27.

TABLE 27 Table “FilterQueueInput” Column Type Modifiers filter_queue_input_key integer not null PK filter_queue_input_uuid uuid not null UK filter_queue_key integer not null UK2 docset_key integer not null UK2 created_dttm timestamp without not null time zone

A detailed description of attributes included in the table structure of Table 27 is shown in Table 28.

TABLE 28 Attribute Description Filter Queue Input UUID Is a UUID of a filter queue input, and is used to process a filter operation by using an XDS method. Filter Queue Designates a filter queue. DocSet Designates a document set.

As described above, when pieces of information about a filter that is to perform an operation is stored in a filter queue, the filter performs the operation as follows according to a type of the filter.

1) Ann internal filter to perform an operation according to a database job manager. The database operation manager periodically calls a function FilterQueue_execute( ). The function is used to find the internal filter in content of the filter queue and then the database operation manager enables the internal filter to perform an operation at a time when the filter has to perform the operation.

2) An external filter performs an operation according to a program FilterProc. The program FilterProc used herein refers to an interface module for realizing an external filter. An external filter will be explained below in detail with reference to FIG. 6.

FIG. 5 is a diagram for explaining an external filter 541 according to an embodiment of the present invention.

A cloud 510 and external apparatuses 520, 530, and 540 connected to the cloud 510 are illustrated in FIG. 5. In this case, the cloud 510 and the external apparatuses 520, 530, and 540 may be connected to each other through wired or wireless communication. For example, the cloud 510 and the external apparatuses 520, 530, and 540 may be connected through, but not limited to, an IHE XDS or Mobile-access to Health Document (MHD) standard protocol. A communication protocol through which the cloud 510 and the external apparatuses 520, 530, and 540 are connected to each other will be explained below with reference to FIG. 6.

An external apparatus may be any apparatus as long as it may communicate with another external apparatus or the cloud 510. For example, each of the external apparatuses 520, 530, and 540 may correspond to, but not limited to, medical equipment, a PC, or a mobile terminal for obtaining diagnostic information of a patient.

The external filter 541 may be included in at least one of the external apparatuses 520, 530, and 540. In this case, the external filter 541 and the cloud 510 may transmit/receive an operation through a program FilterProc. The program FilterProc searches for filter operations to be processed by the program FilterProc by using a designated filter UID, downloads input document sets, performs filter processing, configures generated resultant documents into a new document set, and uploads the new document set. Setting of the program FilterProc will be explained with reference to FIG. 6.

FIG. 6 is a diagram for explaining a communication protocol that is used in a system 600 for providing medical information according to an embodiment of the present invention.

A cloud 610 included in the system 600 and programs 620 and 630 respectively installed in external apparatuses are illustrated in FIG. 6.

Each of the programs 620 and 630 may be any program as long as it may be connected to the cloud 610 through wired/wireless communication.

For example, the program BioPump 620 that transmits bio-signal information 621 to the cloud 610 and the cloud 610 may communicate with each other by using an IHE XDS or MHD protocol. In detail, the program BioPump 620 and the cloud 610 may communicate with each other by using an XDS Provide and Register Document Set protocol or an MHD Put Document Dossier protocol.

Also, in the program Bioroid 630 that receives bio-signal information 622 by using a file Event Recorder and re-transmits the bio-signal information to the cloud 610, an IHE MHD protocol suitable for a mobile environment may be used. An MHD protocol simplifies an XDS protocol to be suitable for a mobile environment.

A protocol used between the cloud 610 and the external filters 650 and 660 may also be an IHE XDS protocol. In detail, the cloud 610 and the external filters 650 and 660 may communicate with each other by using an XDS Registry Stored Query protocol, an XDS Retrieve Document Set protocol, or an XDS Provide and Register Document Set protocol.

The system 600 according to an embodiment of the present invention may use a general-purpose communication standard protocol. Accordingly, any API that is a standard protocol used in the system 600 may be connected to the cloud 640.

Main key values used when the programs 620 and 630 provided in external apparatuses communicate with the cloud 610 by using an XDS or MHD protocol are shown in Table 29.

The external filters 650 and 660 perform an operation through five steps. The five steps through which the external filters 650 and 660 perform the operation are as follows.

In a first step, an operation that is to be performed in the external filters 650 and 660 is generated. In detail, when a filter operation is needed according to a filter condition, the cloud 610 generates a filter queue UUID and a filter queue input UUID in a filter queue (that is, tables of Table 25 and 27).

In a second step, the operation that is to be performed by the external filters 650 and 660 is searched for. For example, the operation that is to be performed by the external filters 650 and 660 may be searched for by using an XDS Registry Stored Query method. In detail, a stored query FindFilterJobs may change a filter operation into an association list as shown in Table 41.

TABLE 41 Cloud database IHE XDS/MHD FilterQueueInput.filter_queue_input_uuid Association.uuid FilterQueue.filter_queue_uuid Association.sourceObject XDSDocSet.docset_uuid Association.targetObject

In a third step, a list of operations that are to be performed by the external filters 650 and 660 is prepared. For example, an association list of searched filter operations forms a a filter job list in a program FilterProc as shown in Table 42.

TABLE 42 IHE XDS/MHD FilterProc.FilterJob Association.uuid FilterJob.docsetList.subjobUUID = FilterQueueInput.filter_queue_input_uuid Association.sourceObject FilterJob.jobUUID = FilterQueue.filter_queue_uuid Association.targetObject FilterJob.docsetList.docsetUUID = XDSDocSet.docset_uuid

The program FilterProc used herein refers to an interface module for realizing the external filters 650 and 660. In other words, the program FilterProc is needed to realize the external filters 650 and 660 that operate in the medical information providing system and designates a method of processing a specific filter/document set. The program FilterProc performs a designated operation according to content stored in a setting file after accessing the cloud by using designated server and port information.

If there is no query file additionally designated in addition to the setting file, a filter designated by a filter UID of the setting file is specified to perform an operation. If there is an additionally query file, filter processing is performed according to content designated in the query file.

Key values that may be used in a filter procedure setting file and a description thereof are shown in Table 43.

TABLE 43 Key Description logLevel Indicates a log level and designates one of the following values. OFF ERROR WARN INFO (default) DEBUG serverHost Is an address of a XDS/MHD server of a cloud. serverPort Is a port number of the XDS/MHD server of the cloud. workingDir Designates a working directory. filenameFormat Designates a file name of documents that are to be downloaded and may use the following keyword. %uid: is replaced by a UID of a document. %dttm: is replaced by a time when the document is generated. %seq: is replaced by a serial number that is automatically assigned. retrieveSetCount Indicates a set count when documents are downloaded. An  HTTP overhead decreases as the set count increases.  However, if the set count is too large, it exceeds a buffer  capacity and thus the documents may fail to be downloaded.  A default value is 1. preprocessor Designates when all of document sets are downloaded and then pre-processing is needed, and may use the following keyword. %inDocSetDir: is replaced by a folder name of an input document set. %inDocSetPathList: is replaced by a path name list of all of document files included in the input document set. %inDocSetFileList: is replaced by a file name list of the all documents included in the input document set. %outDocSetDir: is replaced by a folder name of an output document set. processor Designates a path name and factors called for a document or a document set, and may additionally use the following keyword in addition to the keyword designated in the above preprocessor. %inDocFile: is replaced by a file name of an individual input document. %inJobDir: is replaced by an overall operation folder when two or more input document sets are needed for filter processing. %inJobPathList: is replaced by an overall path name list of all input document files included in an operation folder. %inJobFileList: is replaced by a file name list of the all input documents included in the operation folder. %outDocFile: is replaced by a name of an individual output document file. %outJobDir: is replaced by a name of an output operation folder. postprocessor Designates when document set processing is completed and then post-processing is needed, and may use the same keyword as that of the preprocessor. filterUID Designates a UID of a filter. UIDPrefix Refers to a prefix for UIDs that are generated for metadata. groupIdType Indicates a group ID type and uses “BIS-CLOUD” in a BIS-Cloud unless there is a special reason. docsetClassUID Refers to a class UID value for generated document sets. docsetTitle Is a default title for the generated document sets. docsetComments Is a default description of the generated document sets. mimeType Is an MIME type that is needed to upload a generated document. rename Determines whether documents having used in an operation are to be moved or deleted, and designates true to move the documents and false to delete the documents. A default value is false (delete). repeat Determines whether to repeat. A default value is false (no repetition). repeatInterval Designates a repetition interval. For example, 300 (seconds) may be designated as a repetition interval.

A program FilterProc generates an operation folder under a folder designated with a working directory workingDir as shown in Table 44. The program FilterProc may designate that pieces of content of the operation folder are to be deleted later.

TABLE 44 Folder/Filename Description {workingDir}/FJ-xxxx Input operation folder {workingDir}/FJ-xxxx/output Output operation folder {workingDir}/FJ-xxxx/DS-yyyy Input document set folder {workingDir}/FJ-xxxx/DS-yyyy/output Output document set folder {workingDir}/FJ-xxxx/DS-yyyy/zzzz Input document file {workingDir}/FJ-xxxx/DS-yyyy/zzzz.xml Input document metadata (XDS Document Entry) {workingDir}/FJ-xxxx/DS-yyyy/zzzz.output Output document file {workingDir}/FJ-xxxx/DS-yyyy/DS.xml Input document set metadata (XDS Submission Set)

In a fourth step, the external filters 650 and 660 transmit a result of the operation to the cloud 610. In this case, the external filters 650 and 660 transmit association information as shown in Table 45 before transmitting a document set that is a result of the operation to the cloud 610.

TABLE 45 FilterProc.FilterResult IHE XDS/MHD Auto-generated Association.uuid Created XDSDocSet.docset_uuid or Association.sourceObject XDSDocument.document_uuid FilterJob.docsetList.subjobUUID = Association.targetObject FilterQueueInput.filter_queue_input_uuid APND Association.associationType “FilterJobStatus” Association.slot Name “SubmissionSet” or “DocumentEntry” Association.slot Value

In a fifth step, the external filters 650 and 660 complete the operation. An XDS server XDSServer of the cloud 610 according to an embodiment of the present invention first stores Association.slotName=“FilterJobStatus” in a database before storing the objects DocumentEntry, SubmissionSet, Folder, and Association in the database. In this case, a association_kind column value of an XDSAssociation table is determined according to an Association.slotValue. Then, the XDS server XDSServer stores attributes of the object Association in the database and finally calls a function FilterQueue_update( ) to record that the filter operation is completed. An example is shown in Table 46.

TABLE 46 IHE XDS/MHD Cloud database Association.uuid XDSAssociation.association_uuid Association. sourceObject = XDSAssociation.source_uuid Created XDSDocSet.docset_uuid/ XDSDocument.document_uuid Association.targetObject = XDSAssociation.target_uuid FilterJob.docsetList.subjobUUID = FilterQueueInput.filter_queue_input_uuid Association.associationType = XDSAssociation.association_type “APND” Association.slotName = “FilterJobStatus” Association.slotValue = XDSAssociation.association_kind “SubmissionSet” = JS (FilterJob - “DocumentEntry” SubmissionSet) JD (FilterJob - Document)
